INITIALIZATION
Short Reference • INITIALIZATION ABAP Statement
ABAP Syntax INITIALIZATION.
What does it do? This event keyword defines an event block for initializing an executable program. The associated event is triggered by the ABAP runtime environment during the flow of an executable program, directly after LOAD-OF-PROGRAM and before the selection screen processing of any existing standard selection screen. This enables the input fields of the selection screen to be initialized once-only, including those fields defined in the logical database associated with the program.
